December 13, 2018  NMEA certified, MFD compatible

Loads connected to the Circuit Control YDCC-04 can be managed from all chart plotters with CZone support: this includes all modern models of Garmin, B&G, Lowrance, Simrad, Furuno and recent models from Raymarine (Axiom, eS, gS series). The Circuit Control and Switch Control are certified by NMEA.

We are glad to inform you that our digital switching products was certified by NMEA. The Circuit Control YDCC-04 and Switch Control YDSC-04 have passed certification; they are pure NMEA 2000 products using standard PGNs.

You can manage loads from connected physical buttons, with "virtual buttons" of our Wi-Fi Gateway or automatically, using our sensors. However, of course, there is great demand for management from an MFD screen.

With this update, you can do this from any chart plotter with CZone support, meaning all modern chart plotters of Garmin, B&G, Lowrance, Simrad, Furuno and recent models from Raymarine (Axion, es, gs series).

The only things you need are:

  1. Connect Circuit Control (with 1.01 firmware) to your NMEA 2000 network.
  2. Fill the form with the desired channel names below and download the personalized configuration file for your MFD.
  3. Turn on CZone support on your MFD and configure the Dip Switch setting.
  4. Upload the configuration file to the MFD (usually from MicroSD card).
  5. That is all, now you can manage loads from your chart plotter!

Presentation of controls and the location of controls depends on the MFD manufacturer. Please refer your MFD documentation.

Please be aware about the following limitations in the current firmware version:

  • You can use only one Circuit Control with all your chart plotters, because the downloaded file contains the configuration for one Circuit Control unit only and the configuration file must be the same on all chart plotters with activated CZone support.
  • If you already have CZone equipment installed, you will overwrite the exiting CZone configuration with our file and your CZone equipment will not function properly.

In the next year, we'll publish a detailed manual about integration of our products to networks with existing CZone equipment and add the possibility to use multiple Circuit Control units.

Let's configure the system with B&G Vulcan v7 chart plotter and Circuit Control YDCC-04 unit. For other plotters, the actions will be similar.

STEP 1. Connection of Circuit Control

Please refer the section V of the Manual. You do not need to connect buttons or loads right now. It is enough to connect the NMEA 2000 cable to the Circuit Control.

STEP 2. Generation of CZone file

Please use this form to generate a CZone configuration file (.ZCF) for your MFD. The DIP Switch setting on the MFD must be different from YDCC DIP Switch setting (it is generated by the serial number). For example, you can use 00000001 to configure your MFD.

STEP 3. Turning on CZone support on MFD

Go to "Advanced Settings" of Vulcan and turn on CZone support.

Now, locate the CZone icon in the "Settings" menu, and set "Dip Switch" setting to 00000001 or to any other value not matching with YDCC Dip Switch setting.

STEP 4. Upload configuration to MFD

Save the file downloaded at the STEP 2 to the MicroSD card, insert it to Vulcan and locate "Files" item in the menu. Choose the MicroSD card, locate and import the file.

The chart plotter should show you the "Configuration successful" message after file import.

If you are re-writing an existing CZone configuration (for example, you decided to rename buttons and uploading the configuration file second time), you may need to reboot your MFD after import to apply changes.

STEP 5. Test digital buttons

Now, locate the "CZone" icon in the menu (not in the "Settings" submenu!), tap on the "Control, Monitor" icon and you'll see your buttons as shown at the first picture!

You can switch buttons and hear that relays are switching (they are actually very quiet, because the case is totally filled with rubber) and see that status LEDs of Circuit Control are flashing properly.


The Circuit Control is supplied with the setting "YD:CZONE AUTO", it means that CZone support will be automatically activated in the Circuit Control when the configuration file download from our web site is uploaded to MFD.

If you have more than one Circuit Control unit, CZone support will be activated at the same time on all connected units and caused the conflict. To prevent unnecessary activation, switch this setting to OFF from connected buttons or using software. Please, refer sections VII and X of the Manual.

If you unchecked the automatic activation at the step with CZone configuration file generation, you need to activate CZone support on Circuit Control manually; to do it, configure the setting to ON.

The firmware update 1.01 for Circuit Control is available on the Downloads page. The update procedure is described in the section IX of the Manual.
